CORSET-STEEL FASTENING.

SPECIFICATION forming part of Letters Patent No. 295,171, dated March18, 1884.

Application iilcd September E, 1853.

To aZZ whom it may concern:

Be it known that I, LUOIAN HILL, of North Brookfield, county ofWorcester, State of Massachusetts, have invented an Improvement inCorset-Steel Fasteuings, of which the following description, inconnection with the accompanying d rawings,is a specification, likeletters on the drawings representing like parts.

This invention has for its object the production of a simple andefficient lock-clasp or fastening device composed of a loop-like pieceof metal closed at its outer end, and having one or both of its endsconnected loosely with and so as to be free to move on or with relationto the steel, the inner wall or edge of the loop being shaped to presenttwo stud-receiving openings of different diameter connected by a slot ofless width than the diameter of the stool; of the opposed steel.

Prior to my invention an eye-plate has been employed having its outerend slotted to constitute two spring-arms; but when the said arms aresubjected to considerable strain, or become twisted out of the sameplane, the stud is liable to pass out from the said slot, leaving thecorset loose.

In. another application filed by ine'I have shown a one-piece loch-clasphaving one or more spring-arms located within a plate firmly rivetedupon the steel; but such a lock-clasp requires for its production moremetal and is more expensive to manufacture.

Figure 1 represents asuilicient portion of a. pair of corset-steels toillustrate one embodr ment of my invention; Fig. 2. a section of Fig. lon the dotted line a: m,- Fig. 3, a detail of the fastening device orlock-clasp removed; Fig. 4., a modification; Fig. 5, a detail oi theslotted steel of Fig. 4.; Fig. 6, the lock-clasp of Fig. 4 removed; Fig.7, a section of Fig. 4. in the dotted line m. Fig. Sis yet anothermodification; Fig. 9, a detail of the slotted spring of Fig. 8, and Fig.10 shows the lockclasp of 8 removed.

Referring to the drawings, the steels A B and the headed studs 0 are allas usual. The loclrclasp D is coinposedof a springmetal loop, the freeends (1 cl of which are next the edge of the steel A. The inner edge orwall of the loop D is so shaped as to leave an opening, 2, of greaterdiameter than the head of the stud c, and an opening, 3, of lessdiameter than the head of the said stud, the two openings beingconnected by means of a (No model.)

slot or space, which at some point, as at 4, is of less width than thediameter of the stud 0 below its head.

In Figs. l to 3 the end d of the loop,which constitutes the fastening orlock-clasp, is riveted closely to the stceltA by two rivets, 5 6

but the end d of the said loop has in it ahole or slot of greaterdiameter or area than the diameter of the rivet or pin e embraced by theend (1, so that the said end may move provide the end d with a fixedstud, e, to en'- ter and move in the said slot.

In practice I lind it necessary to have but one end of the fastening orlock-clasp attached to the steel loosely; but I may. as I sometimes findit desirable, connect both the ends at d loosely with the steel A, asmall amount of lost motion being provided for the difference betweenthe diameters of the rivets 5 6 and the slots f f, in which they enter,as in Figs. 8 and 9.

I do not claim a latch operated by a spring, as in United States LettersPatent No. 247,015; nor do I claim a corset-steel combined with alongitudinally-arranged spring or series of wire loops which are adaptedto more laterally with relation to the length of the steel and underbridge pieces attached to the steels, as in United States Letters PatentNo. 238, 7 31.

Iclaini The steel B and its headed stud, combined with the steel A andits an tached clasp D, one end of the said clasp being connected looselywith the said steel, whereby the clasp is permitted to expand laterallyas the stud passes from the larger into the smaller part of the eye ofthe clasp, and then springs back of and locks the said stud in thesmaller part 3 of the clasp, all substantially as set forth.

In testimony whereof I have signed my name to this specification inthepresence of two subscribing witnesses.

LUCIAN HILL.
